Info

Note: In SFTOS 2.3.1.9, these messages also appear when moving from the routing image to the switching image without resetting the configuration to factory defaults from the Boot Menu. This issue results from the use of unique flash file formats. Use one of the following procedures to resolve this condition: • Clear the configuration in flash by resetting the switch to factory defaults. See Restoring the System to the Factory Default Configuration on page 67. • If the first procedure fails, you can format the flash using the Boot Code Utility menu: During the reload, when prompted, press 2 (Boot Menu), then 6 (Run flash diagnostics). Or press 2, then 30 (Boot Code Utility Menu), then 14 (Format File System). Caution: If you are not patient during the formatting, you WILL corrupt the code by interrupting or rebooting. Recovering from a Software Upgrade Failure When an image is downloaded to flash, as shown in Figure 260, SFTOS verifies the image CRC. Switch software can be corrupted during an upgrade by downloading the wrong file to the switch or by deleting the image file. <strong>Force10</strong> S50 #copy tftp://192.168.20.63/F10r2v3m1b9_switching.opr system:image Mode...........................................

Figure 260 Downloading Software to the Switch If you experience a software upgrade failure in 2.5.1, you can revert back to the previous version or another version. See Managing SFTOS Software with SFTOS Version 2.5.1 on page 58. 284 Troubleshooting
Recovering from a Lost Password The default CLI user, admin, has read/write access, with no password until you create one. Once created, the only way to recover from a lost admin password is to reload the switch using facory defaults. See Restoring the System to the Factory Default Configuration on page 67. Alternatively, if the user is not admin, then you can assign a new password to the user. See Creating a User and Password on page 45. Recovering from Switch Stack Problems If a master switch (management unit of a stack) fails, or if a newly added switch in a stack is not recognized, the stacking algorithm in each S-Series switch sets the switch to automatically negotiate with connected units to determine the stack manager and unit numbering. See Management Unit Selection Algorithm on page 104 and Unit Number Assignment on page 104. You can manually intervene by selectively unplugging and reconnecting switches, and by manipulating the values that appear in the algorithm. See Adding a Switch to a Stack on page 107. When a switch cannot transmit packets to a destination stack member, you may see console messages similar to the following: STACK: communication timeout to d8:2e ATP: TX timeout, seq 24554. cli 778. to 1 tx cnt 21. Figure 261 Console Message: communication timeout ATP, in the screen capture, above, refers to the SFTOS task used for stack member communication. These messages point to a communication problem with a stack member assigned an ID of d8:2e, which is derived from the last two digits of the MAC address of the switch. This condition may result from the following: • Bad stacking cables or hardware components (connectors, bus...) • Improperly connected cable • Improperly seated module An RPC timeout message like the following indicates a communication problem between the management unit and the member switch with the MAC address of 0:1:e8:d5:e6:20. The communication problem in this case was caused by the stack cable. RPC - Timeout to CPU: 0:1:e8:d5:e6:20. SFTOS Configuration Guide, Version <strong>2.5.2</strong>.0 285
